NEAT examples

Basic client

The client reads data from STDIN and send it to the server. The received data is written to STDOUT.

client [OPTIONS] HOST PORT

-P : neat properties
-R : receive buffer in byte
-S : send buffer in byte
-v : log level (0 .. 2)

$ ./client -P "NEAT_PROPERTY_IPV6_REQUIRED,NEAT_PROPERTY_SCTP_REQUIRED" -v 2 www.neat-project.org 80

HTTP GET client

neat_http_get sends a HTTP GET request on port 80 to a given HOST and writes the response to STDOUT.

By default the webservers root / is requested - an optional URI argument may be applied.

neat_http_get HOST [URI]

$ ./neat_http_get www.neat-project.org

chargen/daytime/discard/echo servers

These servers are compatible with the client example and should show the basic functionality of the neat library.

  • server_chargen - sends a sequence of ASCII characters until the peer disconnects.
  • server_daytime - sends the current date and time to the peer and closes the connection
  • server_discard - discards all received data
  • server_echo - sends back an identical copy of the data it received
server_[chargen|daytime|discard|echo]

-P : neat property
-v : log level (0 .. 2)
-S : buffer in byte (discard and echo)

tneat

tneat is a performance measurement tool. When runnning as a server, tneat waits for incoming connections and prints statistics about when the connection finished.

As a client, tneat sends -n <num> messages with a size of -l <byte> bytes each to the HOST and closes the connection when finished.

tneat [OPTIONS] [HOST]

-l : message length in byte (client)
-n : number off messages to send (client)
-p : port
-P : neat properties
-R : receive buffer in byte (server)
-T : max runtime (client)
-v : log level (0 .. 2)

server:
$ ./tneat

client:
$ ./tneat localhost
